[Mechanisms of the change in blood electrical conductivity on the administration of dehydrating substances].
After i.v. infusion with 20% mannitol or 30% urea (1.5 g/kg) for 30 min, the specific electrical resistance (100 kHz, AC) of the whole blood decreased by 20-30% in anesthetized cats, although the plasma electroconductivity remained unchanged. Hematocrit, owing to osmotic hypervolemia, was significantly decreased thus causing a drop in the whole blood electrical resistance according to Maxwell's equation.
